My take is that you can never have too much of an ignition system. I've found out on my previous cars that I could always run a a wider gap and was able to richen up my A/R a bit when I upgraded my ignition. It would always be good for about a tenth and 1 mph in the 1/4 mile for me. Closing the gaps on your spark plugs to me is just a way of dealing with the inefficiencies of your present ignition system if you are misfiring. Now presently I'm on the the stock ignition system running Denso spark plugs gapped at 0.25. So far with a 50/50 mix of water/alcohol on 91 octane, I have no misfires what so ever. As soon as I could afford it I would like to upgrade my ignition system and see what it will do. I'll be hopefully be doing a change to E-85 soon and am curious to see what my ignition system will do then.
